1 Claim.

The present invention relates to new and useful improvements in carriageshifts iortypewriters, and more particularly to a foot operated shift.

One of the objects of this invention is to provide a device for shiftingtypewriter carriages which can be readily operated by the person usingthe tyDSwriter, whereby the operator can use his foot to shift thecarriage and increase the speed in using the machine.

It often occurs that a person using the touch system of manipulating thekeys oi a typewriter will not bring his iingers back to rest upon theproper keys after shifting the carriage by hand, thus causing theoperator to strike the wrong keys.

Another object of this invention is to save the time of the operator.When in the course oi copying, it shifts the carriage of the typewriterwithout compelling the operator to remove the eyes from the copy, andobviating the necessity of re-locating the sequence of the last wordprior to the shifting of the carriage.

Another object of the invention is to provide a carriage shifting deviceof the above character which can be readily operated by the foot so thatthe person using the'typewriter will not have to remove his hands fromthe key-board.

A further object of the invention is the provision of a carriageshifting device which can be easily attached to a typewriting machinefor shifting the carriage, either from the right or the left side of thecarriage, according to the type of machine to which the device is to beapplied, or the wish of the operator.

With the above and other objects in view, the invention consists in thenovel features of construction, the combination and arrangement of partshereinafter more fully set forth, pointed out in the claims and shown inthe accompanying drawings, in which Fig. 1 is a top plan View showing mydevice applied to a typewriting machine and looking in the direction ofthe arrows on the line 1-1 of Fig. 2.

Fig. 2 is a front elevation.

Fig. 3 is a side elevation looking in the direction of the arrows on theline 3 3 of Fig. 1.

Fig. 4 is a side elevation of a link type of connecting arm to attachthe device to the carriage.

Fig. 5 is a side elevation of a modiiied type of foot engaging member.

Fig. 6 is a cross sectional view on the linee-6 of Fig. 5, looking inthe direction of the arrows.

Fig. '7 is a sectional View on the line 7--1'7 of Fig. 3, and

Fig. 8 is a side elevation of the foot'engaging member looking in thedirection of the arrows on the line 8 3 of Fig. '7. y

In the accompanying drawings it will benoted that in Figs. 1 to 3,lha-ve illustrated my device as applied to a conventional ltype oftypewriting machine, which is shown in dotted lines and includes theusual carriage 1. y10

The typewriting machine usually rests upon a desk or other support asshown at 2 and the ysupport rests upon the floor, which in the present yinstance is indicated at 3. Secured to the door 3 at one side ofthemachine is a base member 4 upon which is rotatably supported a drum5.

Attached to the drum and extending upwardly therefrom, is a sectionaladjustable standard, which includes the lower section 6, the upper endof which is hollow to receive the lower end of the upper section 7. Theupper section 7, is held in adjusted position relative the lower sectionby means of the set screws 8.

The upper section 7 passes through a guide bracket 9 which is secured tothe desk 2 by means of a clamping screw 10. An adjustable collar 11 onthe section 7 is secured in place by means of a set screw 12, and bearsagainst the bracket 9 for holding the section 7 against downwardmovement. 30

The upper end of the section 7 is extended laterally to form a crank arm13, having a hollow outer end to receive the inner end of an ad justablenger 14. The finger 14 is held in adjusted positions by means of a setscrew 15. The 35 linger has attached to its outer end a pliableconnecting member 16, which in turn is attached to a pin 1'?, at one endof the paper carriage 1.

Extending around the drum 5 for a greater portion of its circumferenceis a iiexible belt 18, one end of which is secured to the drum, whilethe other end is connected to the upwardly extending arm 19, of apivoted crank, the other arm 20, of which extends laterally from thebracket 21. 'I'he crank is pivoted to the bracket 21 by means of thebolt 22, while the bracket is secured to one leg of the desk as shown inFig. 7.

Attached to the arm 20 of the crank is a treadle 23 designed to beengaged by the toe portion of the foot' of the operator, wherebydownward pressure on the treadle will rotate the drum and standard forswinging the nger 14 in the arc of a circle and shift thecarriage 1 toits normal starting position so that the carriage can be readuy shiftedwithout the operator re- 55 moving his fingers from the proper keys ofthe key-board.

In Fig. 4 I have illustrated one form of connecting member 16, whichincludes a plurality of pivotally connected sections 16, to permit theconnecting member to fold after the carriage has been shifted to itsnormal starting position.

In Figs. 5 and 6 I have illustrated a foot piece 23' which is` carriedby a sliding yoke 24 mounted upon the bar 25. The foot piece 23 extendslaterally from the yoke and is to be engaged by the side of the foot asthe foot extends transversely of the yoke 24 when in operative position.The yoke 24 is U-shapedin cross section as shown in Fig. 6, and bolts orpins 26, connect the sides thereof to retain the yoke on the bar 25.

VThe bar 25 has its ends connected to the upstanding end portions of aU-shaped bracket 26, adapted to be attached to the fico-r adjacent oneleg ofthe desk. The foot piece has attached to the rear face thereof, alateral arm 26, the outer end of which may be connected to the belt 18.

' In this form of foot piece the same is engaged by the side of the footand moved along the bar 25 for shifting the carriage.

. From the foregoing, it will be apparent that I have provided a footaccelerated carriage shift which can be used in connection withconventional types of typewriting machines for shifting the papercarriage without the operator having to remove his hands from thekey-board and the eyes from the copy.

The connecting member 16, between the nger 14, and the carriage, is of aflexible or foldable nature, so that should it be desired to shift thecarriage by hand, it can be easily done without operating the foottreadle 23. The device is very simple in its construction, and can bemanufactured and placed upon the market at a very low cost.

While I have shown and described the preferred embodiment of myinvention, it will be understood that various changes and alterationscan be made when putting the invention into practice without departingfrom the spirit of the invention, or the scope of the appended claim.

What I claim is:

In combination with a typewriter including a movable carriage and asupport for the typewriter, a base member adjacent the support, arotatable drum mounted upon said base, a sectional adjustable standardcarried by said drum and disposed ina Vertical plane, a guide bracketcarried by the support and embracing the upper portion of the standard,means for retaining the upper portion or" the standard against downwardmovement relative to the bracket, a lateral integral extension at theupper end ofthe standard,

Va nger adjustably connected to the lateral extension, and a pliableconnecting unit between the nger and the carriage.
